RA lL-STRAlGHTENlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 266,536, dated October24, 1882.

Application filed April'fi, 1882. (No model.)

To all whom it may concern Beitknown that I, WILLIAM K. SEAMAN, acitizen of the United States, residing at Scranton, in the county ofLackawanna and State of Pennsylvania, have invented new and usefulImprovementsin Rail-StraighteningMachines, of which the following is aspecification.

This invention relates to a machine which is intended for taking outlateral kinks from the rails, and to deliver them free from suchimperfections to the cambering-machine. The novel construction of myrailstraightening machine which forms the subject-matter of this presentinvention is pointed outin thet'ollowing specification.

In theaccompanying drawings, Figure 1 represents a side view of mymachine. Fig. 2 is a transverse vertical section in the plane or no,Fig. 1.

Similar letters indicate eorrespondingparts.

In the drawings, the letter A designates a frame, which consists of abed-plate, B, from which rise two standards, 0 U, the standard 0 beingcast solid with the bed-plate, while the standard (J is held in positionby the traverses I). In each of the standards 0 O are mounted fiveshafts, E and F, respectively, and on each of these shafts is mounted aroller, G or II. The shafts E E E E E are shown in Fig. l of thedrawings, and on these shafts are tirmly mounted the rollers G G G G G,which are indicated in dotted lines in Fig. 1, and two of which areshown in Fig. 2. The shafts E E E E E have their bearingsin eccentricbushes I I I I 1 which are mounted in the standard (J, and can be turnedin their hearings, so that by turning said bushes the position of therollers G G G G G in relation to each other is changed. This will bereadily understood by referring to Fig. l, where the center of the shaftE is designated by a and the center of the bush 1 by b. By turning thebush in the direction of arrow 1 the axle E, together with its roller G,is raised, and by turning the bush in the opposite direction the axle15*, together with the roller G is depressed. From each of the bushes II I I 1* extends an arm, J J J J J, and from the arm J extends a lever,K, which connects with the arms J J by a. rod, L, and with the arm J bya rod, M, said arm J being connected to the arm J by a rod, N. Bypushing the lever K in the direction of the arrow marked near it in Fig.1 all the bushes I I I I l are turned in the direction of arrows l, andthe rollers G G G are moved down and the rollers G G are moved up. Therollers G G G G G are intended to bear upon the head of the rail, asshown in Fig. 2, and bythe action ofthc lever K said rollers can bereadily so adjusted that they produce the desired efi'ect upon the rail.In the arms'J J J J J are formed segmental slots 0, through which extendscrewstuds (7, provided with nuts 0. When the rollers G G G G G- havebeen adjusted in the required position the arms J J J J J are locked bymeans of thenuts c, and the rollers cannot change their position untilthe nuts are released.

The rollers H H H H H, which are mounted on the shafts F, bear upon theflange of the rail, (see Fig. 2,) and they are adjusted in the requiredposition by means of the lever K precisely in the same manner in whichthe rollers G G G G G are adjusted. The rails as they pass from thefinishing-rolls are carried forward by aseries ot'grip-rollers, whichalso serve to introduce the rails into and push them through thestraightening-machine, when they are received by another set ofgrip-rollers, formingpart ot' the camberingmachine. As the rails passthrough the straighteningmachine all lateral kinks existing in the sameare removed, the action of the straightening-rollers beingadjusted bymeans of the levers K K.

If desired, the rollers G and H may be provided with flanges to confinethe rails in the proper course, or said rollers may be slightlytapering. If necessary, the rollers H may be provided with grooves toconform to the edges of the flanges of the rails and to prevent saidflanges from getting injured.

My machine may also be used for straightening cold rails, and in thiscase it may be of advantage to impart to some of the rolls a positivemotion by suitable gearing.

What 1 claim as new, and desire to secure by Letters Patent, is
